Gypsum plaster is a white cementing material made by partial or complete dehydration of the mineral gypsum, commonly with special retarders or hardeners added. Applied in a plastic state (with water), it sets and hardens by chemical recombination of the gypsum with water.
Drywall (also known as plasterboard, wallboard, sheet rock, gypsum board, buster board, custard board, or gypsum panel) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, fiberglass, or a

#0183;#32;If plaster or gypsum is heated to between 130 #176;C, (266 #176;F) and 180 #176;C (350#176;F), hemihydrate is formed, which will also reform as gypsum if mixed with water. [21] [22] On heating to 180 #176;C (350#176;F), the nearly waterfree form, called anhydrite (CaSO 4 #183; n H 2 O where n = 0 to ) is produced. Anhydrite reacts slowly with water to return to the dihydrate state, a property exploited in some

Gypsum is a sedimentary rock and a crystalline mineral. Gypsum is a soft, white to gray, quot;chalkyquot; mineral composed of calcium sulfate and water, says Raymond Anderson of Iowas Department of Natural Resources. Gypsums chemical symbol is CaSO42H2O.
How Gypsum is Made Editors Note: The following article is based on information supplied by Gold Bond It describes Gold Bonds manufacturing process. Other gypsum manufacturers may differ in certain characteristics from the process described below. Chemists call it CaSO 42H
Gypsum board is the most common indoor building material in the United States. In the United States and Canada, gypsum board is manufactured to comply with ASTM Specification C 1396 which was designed to replace several existing ASTM specifications, leaving one reference standard for all gypsum
GYPSUM PRODUCTION PROCESS. Gypsum production plant is a calcination unit for production of powdered gypsum (calcined). Gypsum which is coming from pit is brought to the appropriate size with gypsum jaw crusher. The hammer crusher then moves to the kiln feed size. As a result of crushing process, the gypsum size is 010 mm and the crushed
British Gypsum currently has 5 main manufacturing locations throughout England, each close to significant gypsum reserves. British Gypsum also provides the industry''s foremost training through the market leading SaintGobain Technical Academy.
Gypsum deposits occur in many countries, but Spain, Thailand, the United States, Turkey, and Russia are among the leading producers. The largest gypsum crystal was found in the Braden mine in Chile and exceeds 3 metres (about 10 feet) in length and metre (about feet) in diameter. In the, commercial sedimentary gypsum deposits occur in New York and Michigan; others of economic
To produce gypsum board, crushed natural gypsum or synthetic gypsum is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of recycled paper on a long board machine.
